The second set in the Timewalkers block that features legendary characters from the Warcraft and Warcraft 2 eras (see "'WoW TCG Set 20: Timewalkers--Betrayal of the Guardian'"). Players will be able to add even more Humans, Night Elves, Orcs, and Tauren to their racial decks while taking advantage of new abilities and allies. A new keyword, "Rift" is introduced in the set, and it will allow those who maintain the integrity of the timeways access to powerful abilities, allies, and equipment much earlier in the game than ever before.
